Kenworth’s integrated powertrain has been engineered to maximize fuel economy, reliability and performance while delivering The World’s Best® driving experience.

PACCAR’s new 40K tandem rear axle — the industry’s premier line haul axle — is precisely matched to deliver power to the asphalt with minimum loss. Featuring an advanced, robust design that trims vehicle weight by up to 150 pounds, the PACCAR axle delivers more fuel efficiency, uptime and payload.

“I haven’t been this excited about truck specs in a long time. Our newest spec saves weight, provides nearly a 20 percent boost in fuel economy in our tanker fleet and a 15 percent bump in our freight fleet, and has our drivers raving about the comfort… We drive 4.2 million miles per year, and each 5 percent jump in fuel economy gives us a 1 percent gain to our bottom line…”

-Adam Lindsay, Vice President, Alpha Transport, Salt Lake City

“The T680 is a really nice truck to drive, with a comfortably sized cab and excellent steering response. Perhaps the most (or least) noticeable aspect of the truck is how quiet it is. Driving the truck was simply a joy. It’s easy to maneuver but very solid feeling. It smooths out the bumps and jolts, but it’s not sloppy about it, and you never lose the feeling of where the wheels are on the road. My short drive left me wanting more, but my impression was that this truck could set ride and driver environment benchmarks for some time to come.”

-Jim Park, Equipment Editor,

“I first saw the T680 at the 2012 Mid-America Trucking when it was first unveiled… I talked with Preston Feight (Kenworth assistant general manager for sales and marketing) and his enthusiasm for the T680 was contagious. He was very passionate about how the truck was engineered from the ground up and designed with drivers in mind. He showed me every detail and that stuck with me as I looked at other trucks at the show. I didn’t see anything that compared to the T680.”

– Matt Handte, Executive Vice President for Tribe Transportation,  Georgia

“I just had to switch from a 680 to a [Freightliner] Cascadia. I miss my KW. The differences are all in the details… I feel the 680 is better thought out in those details than the Cascadia.”

– Errol V, Driver, Moderator at

“It is good to see the manufacturers cater to the 5′ female. Our 780 and the T680 allow [Danielle, wife] to easily get a comfortable driving position and reach all switches.”
